IM PROVEM ENT IN SNOW-FLANGERS.

Specification forming part of Letters Patent No. 215,328, dated May 13,1879; application filed February 4, 1879.

To all whom 'it may concern:

Be it known that I, DAVID A. COX, of Pine Bush, in the county of Orangeand State of New York, have invented a new and Improved Snow-Flanger, ofwhich the following is a specification.

Figure l is a vertical transverse section of a car-truck having myimproved iianger attached. Fig. 2 is a vertical section taken on line x.c in Fig. 1. Fig. 3 is a transverse section of one of thespring-Scrapers, taken on line y y in Fig. l, looking downward.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide a device for removing snow fromthe inner side ofthe track-rail, to make way for the flange of thecar-wheel.

The invention consists in a spring plow or scraper pivoted to one of thetruck-timbers, or to a timber carried by the truck or car, said scraperbeing slotted, so that it may slide vertically on its pivot. The scraperis pressed downward by a spring, and is curved so that it will be thrownoutward against the trackrail by contact with the snow.

Referring to the drawings, A is a car-truck of the usual description, inwhose beam B there are mortises a, for receiving the scrapers C. TheScrapers G consist of plates of steel, each having a slot, b, forreceiving the pin c, upon which the plate swings. The plate is tapered,being narrowest at the upper end, and has a projection, c, at the outeredge, on its lower end, from which it is cut off diagonally, formi ngthe beveled edge cf. Its inner corner, j', is rounded and curvedbackward, so that as the scraperis moved forward through the snow itwill be forced against the trackrail. Aflat spring, g, is attached tothe beam B, and presses downward upon the upper end of the scraper. Infront of the scraper, in the mortise c, a rubber spring, h, is placed onthe pin c. As the car moves forward, the lower end ofthe scraper comesin contact with the snow, and forces the snow from the rail toward thecenter of the track.

The engagement of the curved portion of the scraper with the snow forcesthe scraper against the rail, and insures a thorough clearing of the wayfor the iiange of the car-wheel.

The scraper yields to any obstruction, and will readily pass over frogsand crossings, the

projection c clearing the groove in the frog or f crossing. Should thecar stop while the scraper is on the crossing-plank, and then be backedup, the scraper will yield by sliding upward in the mortise.

This improvement may be applied to any truck on a train, or to someportion of the car; but it more properly belongs to the pilottruck ofthelocomotive. It may also be arranged to remove the snow from the outsideor top of the track.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The slotted and curved spring-plate C, the springh, and the truck-beam B, in combination, substantially as herein shownand described.

2. A car-truck scraper curved, tapering toward the top, beveled at f,and provided with projection c, as and for the purpose specified.

DAVID A. COX.
